Both Husky and Stihl know they compete and adjust their prices in any one class to be "close"...
You also can't compare discount to list. If you pay full list for an 880,... what can I say... there a few good $$ in that saw and most dealers will give some relief. A $100 here and there at "list" make little difference - in the 880 the added HP and fully adjustable carb can justify that.
When comparing discount prices, there is also the question of whos bar/chain is shipped with the saw...
In any case, I don't really care about a second or two here and there, and that's why I don't fall all over myself to port much more than the muffler in any saw.
